The C-Class Coupé gets different seats to the saloon, being deeper and more supportive, and they are very comfortable even for long journeys, particularly since all models get four-way lumbar support adjustment, part-electric adjustment, extendable thigh support and heated seats. AMG Line cars get full electric seat adjustment, too.
It’s a good driving position. There’s decent forward visibility, albeit a slightly restricted view out to the rear three-quarters and through the narrow rear windscreen – but nothing unusual for a coupé.
All models get a 10.25in colour screen with rotary and touchpad controls. This looks great, but it can be tricky to use on the move because the menus aren’t always the easiest to figure out. It gets easier with familiarity, though, and most of the control switches on the dashboard are where you’d expect them to be.
The screen can be augmented with a 12.3in digital instrument cluster that has sharp graphics, but isn’t quite as configurable as Audi’s system. It’s standard on the C63 and C63 S, but optional elsewhere in the range. Smartphone connectivity is an option on regular and C43 models, but standard on the two C63 variants.
There’s a real aura of quality to the interior, with a plush mix of leatherette (or soft nappa leather in the two C63 models), metal and gloss plastics living up to the prestige badge. There are some areas lower down the interior where the car doesn’t feel quite as solidly put together as the BMW 4 Series, but generally it feels well screwed together and has a really sumptuous feel.
